Improving the Reliability of Optimised Link State Routing in a Smart Grid Neighbour Area Network based Wireless Mesh Network Using Multiple Metrics

“…This paper was used to highlight the use of the OLSR routing protocol in NAN. Since the performance of these applications has to be determined in objective terms against a set of pre-defined QoS attributes, such as delay and packet delivery ratio, in [12], the conference paper "Multiple Metrics-OLSR in NAN for Advanced Metering Infrastructures" presented the possibility of using AHP and multiple metrics in OLSR for NAN-based WMN to support QoS for the different application traffic types. This was achieved by presenting a case study to show the application traffic best supported by a link metric type and a demonstration of how the AHP algorithm (Equations (3), (5) and (7)) can be used to map paths calculated by a link metric to an application traffic type.…”

“…This was achieved by presenting a case study to show the application traffic best supported by a link metric type and a demonstration of how the AHP algorithm (Equations (3), (5) and (7)) can be used to map paths calculated by a link metric to an application traffic type. The improvement of this article compared with [11,12] is that this article presents an implementation of the AHP in ns-2 using a simulation topology that represents a worst case scenario of AMI activities (where all smart meter nodes are transmitting four different application traffic types simultaneously to a data concentrator) in a five by five grid size NAN-based WMN. Equations (3), (5) and (7) are a demonstration of how the AHP is calculated, and they reference the proposed methodology presented in the second conference paper.…”

“…The metrics are then assigned weights in the range of [0, 1], where the sum of all of the weights equals one. For example, if two RLMTs are considered and anprpcm is set as [0.5, 0.5] (which means both metrics have equal priorities), then the total score for each path is expressed as: The weights were decided through a case study on RLMTs to find the one best suited for each application traffic as presented in [12]. The total normalised score of path j used in the communication between Nodes 0 and 8 is presented in Table 2.…”
